* Get rid of GetProcessId in Win32/Program.inc.Mikhail Glushenkov2009-09-15
| | | | | | | GetProcessId was introduced only in XP. As a bonus, this change makes Program objects copyable, since Program is now basically a PID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81826 91177308-0d34-0410-b5e6-96231b3b80d8

* Add early coalescing to liveintervals. This is work in progress and is known ↵Evan Cheng2009-09-14
| | | | | | | | | to miscompute some tests. Read it at your own rish, I have aged 10 year while writing this. The gist of this is if source of some of the copies that feed into a phi join is defined by the phi join, we'd like to eliminate them. However, if any of the non-identity source overlaps the live interval of the phi join then the coalescer won't be able to coalesce them. The early coalescer's job is to eliminate the identity copies by partially-coalescing the two live intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81796 91177308-0d34-0410-b5e6-96231b3b80d8

* Change MCAsmStreamer to take an MCInstPrinter instead of a Chris Lattner2009-09-14
| | | | | | | | | | | | | full AsmPrinter, and change TargetRegistry to keep track of registered MCInstPrinters. llvm-mc is still linking in the entire target foo to get the code emitter stuff, but this is an important step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81754 91177308-0d34-0410-b5e6-96231b3b80d8

* replace printBasicBlockLabel with EmitBasicBlockStart,Chris Lattner2009-09-13
| | | | | | | | now that printBasicBlockLabel is only used for starting a MBB. This allows elimination of a bunch of arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81684 91177308-0d34-0410-b5e6-96231b3b80d8
* devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden.Chris Lattner2009-09-12
| | | | | | | | | Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that we only have one place that decides what to name bb labels. Hopefully various clients of printBasicBlockLabel can start using GetMBBSymbol instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81652 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman2009-09-11
| | | | | | | | | | | | | | | | working. To support this, add an is_displayed() function to raw_ostream, and generalize Process::StandardOutIsDisplayed and friends in order to support it. Also, call RemoveFileOnSignal before creating a file instead of after, so that the file isn't left behind if the program is interrupted between when the file is created and RemoveFileOnSignal is called. While here, add a -S to llvm-extract and port it to IRReader so that it supports assembly input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81568 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | (uniqued if unnamed) global variable name with the prefix that it is supposed to get. It doesn't do "mangling" in the sense of adding quotes and hacking on bad characters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81505 91177308-0d34-0410-b5e6-96231b3b80d8

* Added the ParseInstruction() hook for target specific assembler directives soKevin Enderby2009-09-10
| | | | | | | | | that things like .word can be parsed as target specific. Moved parsing .word out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes for other targets that support the .word directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81461 91177308-0d34-0410-b5e6-96231b3b80d8

* remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner2009-09-09
| | | | | | | | | | | | | | | the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8
* Added an abstract superclass, MCDisassembler, forSean Callanan2009-09-09
| | | | | | | | | | | | | | all disassemblers. Modified the MemoryObject to support 64-bit address spaces, regardless of the LLVM process's address width. Modified the Target class to allow extraction of a MCDisassembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81392 91177308-0d34-0410-b5e6-96231b3b80d8

* Make TypeBuilder's result depend on the LLVMContext it's passed.Jeffrey Yasskin2009-09-09
| | | | | | | | | TypeBuilder was using a local static variable to cache its result.

Also, optimize Loop::verifyLoop, since it gets called a lot. Use searches on a sorted list of blocks instead of calling the "contains" function, as is done in other places in the Loop class, since "contains" does a linear search.
